China continues to be the leading destination for Brazilian soybeans, and the Brazilian soybean industry wants to further deepen this relationship, expecting historically high volumes in the coming months, the Brazilian Association of Soybean Growers (Aprosoja Brasil) told the Global Times on Friday.
Brazilian soybean exports to China have remained very strong. China imported 12.08 million tons of soybeans from Brazil in June, up 13.7 percent year-on-year, while imports from the US fell 20.9 percent year-on-year to 1.27 million tons, according to data from the General Administration of Customs.
China imported 34.75 million tons of soybeans from Brazil during the period, up 9.1 percent year-on-year, according to Aprosoja Brasil. "Based on arrivals and customs clearance in China, there was clear growth," the association said.
According to the official data platform Brazilian Comex Stat, which records shipments at origin, 48.32 million metric tons were destined for China from January through June, largely unchanged from 48.41 million metric tons during the same period in 2025.
The difference between the two datasets mainly reflects timing and methodological differences between the recording of departures, cargoes in transit, arrivals and customs clearance.
Aprosoja Brasil said that the broader economic conclusion is the same: "Trade flows remained historically strong, China continued to be the leading destination for Brazilian soybeans, and Brazil's total soybean exports reached a first-half record of 69.57 million metric tons."
For farmers, strong export volumes help support the marketing of the crop, although record exports do not automatically mean record farm margins, said the Brazilian industry association.
China is the world's largest soybean importer. Imported soybeans are mainly used for oil production and animal feed. In terms of trading partners, China mainly imports soybean-related products from Brazil, the US, Argentina, Uruguay and Canada.
Brazil ranks among the world's leading soybean producers and exporters, with China being its largest export market for soybeans, according to the Xinhua News Agency. 
Commenting on the significance of the Chinese market, Aprosoja Brasil said "China is absolutely strategic to Brazil's soybean industry," citing data showing that in 2025, China purchased 85.4 million metric tons, representing approximately 79 percent of all Brazilian soybean exports.
The two countries also have a highly complementary trade relationship. For Brazilian farmers, Chinese demand provides scale, market liquidity and greater capacity for long-term planning, said the Brazilian soybean industry association. For China, Brazil offers large, competitive and reliable supplies, as well as a crop calendar that complements production in other supplying countries.
Previously, policy shifts, such as US unilateral tariff measures, have caused disruption for US soybean farmers and other agricultural producers, Lü Xiang, research fellow at the Chinese Academy of Social Sciences, told the Global Times. 
At the same time, China has been diversifying imports, including from Brazil and Argentina, to reduce risks from trade uncertainty, according to Lü.
Aprosoja Brasil noted that this partnership should not be seen merely as a temporary consequence of trade disputes involving third countries. Instead, it is a structural and mutually beneficial relationship, based on the complementarity between Brazil's production capacity and China's large demand for food, animal feed and protein, the industry group said.
Looking ahead to the soybean trade for the rest of the year, Aprosoja Brasil said that they are positive, while having a prudent mindset. Brazil has completed the harvest of a record soybean crop of approximately 180.6 million metric tons, and Brazilian soybean exports are expected to reach 116.3 million metric tons in 2026, which would also be a record, the association said.
"Brazil therefore has sufficient supply to continue serving the Chinese market strongly in the coming months... We expect historically high volumes, although not necessarily growth every single month, because soybean trade is seasonal and Northern Hemisphere supplies become more prominent during the second half of the year," it said.
。这是国内首个基于商业运载火箭末级改造的长时间留轨平台，首次完整实现“入轨转换 — 轨道机动 — 在轨试验服务 — 精准离轨”的全流程技术闭环，为我国商业航天探索低成本、高效率的在轨服务新模式提供了支撑。爱神星一号留轨平台是星河动力打造的创新型在轨试验及在轨服务基础设施，其核心技术路径是将运载火箭末级进行在轨适应性升级，通过改进热控、能源、姿控等系统，使原本完成卫星释放任务后即结束使命的火箭末级，转化为可长期驻留轨道的通用在轨服务平台。从星河动力航天官方公告获悉，2024 年 6 月 6 日，爱神星一号 01 平台随谷神星一号 Y13 运载火箭进入 535km 太阳同步轨道。

二 | 在完成主卫星释放任务后，火箭末级顺利完成在轨形态转换与系统标定，随后机动至 580km 预定工作轨道，正式开启两年在轨服役。在轨期间，爱神星一号 01 平台先后完成了自身全系统功能验证、长期空间环境适应性考核，并搭载毫牛级电推进等多类商业载荷开展在轨技术验证，为客户提供了真实空间环境下的器件测试、技术迭代数据支撑，覆盖新器件验证、航天新技术试验等多个应用场景。本次任务收官阶段，爱神星一号 01 平台顺利完成在轨安全测试后精准执行机动离轨，全程控制平稳、落点精度达标，验证了自研轨姿控动力系统长期待机后的可靠性与机动精度，也为商业留轨平台的全生命周期管理积累了关键工程数据。

三 | 作为国内首个实现全流程闭环验证的商业火箭末级留轨平台，爱神星一号 01 平台的圆满收官，验证了“火箭末级复用 + 在轨服务”商业模式的技术可行性与工程实用性。继爱神星一号 01 平台之后，爱神星一号 02 平台已于 2025 年 9 月随“鹊桥仙”任务发射入轨，形成双平台在轨服务能力，未来可承接更多批次、更多类型的商业搭载服务。

四 | 面向后续发展，星河动力航天将持续迭代留轨平台技术体系，计划于 2027 年发射专属算力技术验证留轨平台，重点开展太空算力关键技术在轨验证，支撑星上智能处理、在轨数据计算等前沿方向的技术攻关。
